The point estimation based on the given interval limits is 0.706.
<h3>What is a point estimate?</h3>
The use of sample data to compute a single value that will serve as a "best guess" or "best estimate" of an unknown population characteristic is referred to as point estimation.
The point estimation based on the given interval limits is,
Point Estimate = (0.688+0.724)/2 = 0.706
Hence, The point estimation based on the given interval limits is 0.706.

Do you understand why?
If not...be sure to leave comment telling me what u r having problem with.
Glad to help!
i hope i am clear and correct
Answer:
The liquid us Mercy.
Step-by-step explanation:
First we have to find the density of the liquid on dividing the weight by
volume.
Also convert the liters into centimeter cubes by multiplying with 1000 (as there are thousand cm cubes in one liter)
i.e.
volume = 4.7×10^-3 Liter
= 4.7×10^-3 ×10^3
= 4.7 centimeter cube
Now the density is .:
which is the density of Mercy
Thus the liquid is Mercy.
Regression line is given in the form of: y = a + bx
Where b is the gradient
Working out 'b'
Σxy - [ΣxΣy]/N
Σx² - [Σx]²/N
Working out 'a'
a = [∑y/N] - b[∑x/N]
a = [2650/460] - 0.264[3920/460]
a = 5.86 - 2.25
a = 3.61
Regression line equation is
y = 3.61 + 0.264x
